Question

sobre teorema de Tales calcule x e y, sabendo que a// b // c

Answer 1

TEOREMA DE TALES

$\frac{5}{10} = \frac{4}{x} \\ 5x = 40 \\ x = \frac{40}{5} \\ x = 8$


$\frac{4}{8} = \frac{6}{y} \\ 4y = 48 \\ y = \frac{48}{4} \\ y = 12$

Answer 2

5/4=10/x

1/4=2/x

x=8

4/6=x/y

4/6=8/y

1/6=2/y

y=12
